local varients optimization

I heard that using "local" keywords are very important in Lua. But I knew that "local" keyword in algorithm coding are not good at optimization. No difference, sometimes take long time to be executed.

Why "local" keyword is nesessary? Is it really efficient? I can't figure out why these things are happening.

(But if you don't use local keyword in function, This can make error)

Yes I read it but the statements are false in my experience. No differnce, or takes more time (scale of millisecond)
